Title: Innovations by Jean-Claude Le Bastard

Introduction

Jean-Claude Le Bastard is a notable inventor based in Toulouse, France. He has made significant contributions to the field of aerospace engineering, particularly in the development of advanced control systems for aircraft and helicopters. With a total of 3 patents to his name, his work has had a profound impact on flight safety and control.

Latest Patents

One of his latest patents is an actuator servo-control monitoring method and device. This invention enhances actuator displacement servo-control for aircraft flight controls by integrating a hydraulic circuit that provides hydraulic failure indications. The system generates servo-control based on actuator position and a computed position set-point. An alarm phase is activated upon detecting a servo-control error, which remains active as long as the error persists. During this phase, the system assesses whether the actuator is in blocked or divergent states, determining the necessary actions based on the duration of the alarm phase and hydraulic circuit indications.

Another significant patent is a device for compensating for the mechanical play of helicopter flight controls. This invention addresses the challenges posed by mechanical play in automatic piloting equipment for helicopters. The device utilizes a series of mechanically irreversible rams that respond quickly and have short strokes, which are placed in series on the flight controls. It includes detectors to identify the direction of displacement instruction variations and a play compensator that adjusts the instruction based on the detected direction, effectively mitigating the impact of mechanical play.
